 Generally there is resistance to trying to emulate 'undocumented matlab'.
the matlab docs dont specify any predefined formats including FFF.  But, it
does provide for automatic recognition of the FFF string. So it appears
that Matlab's autorecognition does understand the format, despite the
datevec text saying: " If you do not specify formatIn, then DateString must
be in one of the following formats..." (none of which include FFF)

I don't think people would want to mess with the pre-defined formats, since
they're a compatibility item.  There could be an argument made expanding
the autorecognition, though.
